NPM in post-mitotic neurons

In vivo model In vitro model Impact on cell viability Effect on NPM Reference
Spinal cord injury
Mice injected with recombinant human G-CSF following hemisection of the right hemicord G-CSF treated neurons isolated from the spinal cords Neuroprotection and locomoter recovery following G-CSF treatment In vivo upregulation of NPM expression 82
NPM inhibition partially blocked G-CSF neuroprotection
Excitotoxicity
PS1 M146V mutant transgenic mice Glutamate-induced excitiotoxicity of cortical neuronal cultures Decreased survival rate Decreased expression of NPM mRNA 84
NMDA-induced excitiotoxicity in the cerebral cortex of mice PC12 cells Protection against SIAH1-GAPDH induced death NPM disrupts SIAH1-GAPDH complex 85
NMDA-treated primary cortical neurons Overexpression in cortical neurons and mice inhibited NMDA-induced toxicity by inhibiting SIAH1
Kainic acid (KA)-induced excitiotoxicity in rats KA-treated primary cortical neurons and SH-SY5Y cells Decreased NPM shows increased p53 levels in KA-treated SH-SY5Y cells Downregulation of NPM protein in degenerating neurons of the hippocampal CA1 region of KA-treated rats and KA-treated primary cortical neurons 86
NE-4C cells Apoptosis following NPM downregulation is p53-independent
Nucleolar Stress
Cultured cortical neurons treated with camptothecin Reduced rRNA transcription and p53-mediated apoptosis Nucleoplasmic relocalization from nucleoli 111
TIF-IA knockout in neural progenitors and hippocampal neurons Impaired nucleolar activity and increased p53 levels Nucleoplasmic relocalization from nucleoli 112
Rapid apoptosis in neural progenitors
Prolonged degeneration in the hippocampus
Post-mortem brain sections of PD patients Nucleolar damage in human PD brains Nucleoplasmic relocalization from nucleoli 113
TIF-IA knockout in dopaminergic neurons of mice TIF-IA knockout results in parkinsonism in mice
Mice injected with MPTP Increased p53 levels
Downregulation of mTOR activity
TIF-IA knockout in medium spiny neurons of R6/2 mice Late progressive striatal degeneration Nucleoplasmic relocalization from nucleoli 114
p53 prolongs survival through PTEN upregulation, inhibition of mTOR signaling and activation of autophagy
